摘要: 真空吸尘式清扫车是一种利用负压工作的新型清扫车辆。吸尘口是其气路系统的关键部件,对整台清扫车的吸尘能力、吸尘效率以及工作可靠性等各方面有着决定重要的影响。以吸尘口为研究对象,采用UG软件建立吸尘口的三维模型,使用Gambit软件进行网格离散,运用Fluent软件进行流场分析,对不同的卷边吸尘口进行吸尘效果的对比研究,设计出了一种前曲面挡板的吸尘口,并进行了气固两相流的运动仿真验证。研究表明:前宽后窄、带有前曲面挡板的吸尘口具有良好的吸尘效果。Abstract: The vacuum cleaning vehicle is a new kind of sweeper which uses negative pressure. Its dust suctionmouth,as a key component of its gas path system,plays an important role in dust-sucking capability,cleaning effi-ciency,reliability and other aspects of the sweeping vehicle. Taking the dust suction mouth as research object,athree-dimensional model of the dust suction mouth was built with UG software. Grid was generated with Gambit soft-ware,and flow field was analyzed with Fluent software. Theeffects of different structures of the dust suction mouthwith curled edges on the dust suction were compared; a dust suction mouth with front curved plate was designed,and simulation of the gas-solid flow motion was completed. The simulation results show that the dust suction mouthwith wide front edge or narrow rear edge or curved front plate has excellent dust suction effects.
